Let it be, Nevermind and Saturday

Saturday will be an interesting nexus in the musical universe. Feb. 9, 2013 marks the 7,810th day to have passed since Nirvana's "Nevermind."

This is not a nice round number or anything, so on the surface it's not important. Except for this:

On May 8, 1970, the Beatles released their final album, "Let It Be." The Beatles are the best rock 'n' roll band ever.

7,810 days later (September 24, 1991), Nirvana released "Nevermind," which is widely considered to have forever-changed popular music and (though its only OK) is possibly the most important album ever.

There has been the same amount of time between "Let It Be" and "Nevermind" as there has between "Nevermind" and today (really Saturday).

This brings me to a number of conclusions.

1) I feel really old. Even older than that time that cheerleader called me, "sir."

2) I'm not sure which timeframe seems more significant. If you'd asked me two years ago, I would have told you the gap between the Beatles and Nirvana seemed much bigger, but not now. Music today seems to have nothing in common with grunge-era rebel-music.

3) Musically, the current era has more in common with the late 60s and early 70s than it does with the 90s. Songs are (more or less) about having fun, which beats being miserable any day.

4) I'm old.

Do I sound like a helicopter?
